在WinForms中,将按钮添加到ListView中需要使用自定义控件和事件处理程序。以下是一个简单的示例,说明如何将按钮添加到ListView中:
listView1.Columns.Add("Button", 100);
public class CustomListViewItem : ListViewItem
{
public Button Button { get; set; }
}
public class ButtonHost : Control
{
public Button Button { get; set; }
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
Button.Location = new Point(0, 0);
Button.Size = Size;
Button.Visible = true;
Button.BringToFront();
}
}
public class CustomListView : ListView
{
protected override void OnCreateControl()
{
base.OnCreateControl();
View = View.Details;
OwnerDraw = true;
DrawItem += CustomListView_DrawItem;
DrawSubItem += CustomListView_DrawSubItem;
}
private void CustomListView_DrawSubItem(object sender, DrawListViewSubItemEventArgs e)
{
if (e.ColumnIndex == 0)
{
e.DrawDefault = true;
}
}
private void CustomListView_DrawItem(object sender, DrawListViewItemEventArgs e)
{
e.DrawDefault = true;
}
}
private void AddButtonToListView()
{
var listViewItem = new CustomListViewItem();
var buttonHost = new ButtonHost();
var button = new Button();
button.Text = "Click me";
button.Size = new Size(100, 30);
button.Click += Button_Click;
buttonHost.Button = button;
listViewItem.SubItems.Add(new ListViewItem.ListViewSubItem(listViewItem, ""));
listViewItem.SubItems[1].Tag = buttonHost;
customListView1.Items.Add(listViewItem);
}
private void Button_Click(object sender, EventArgs e)
{
MessageBox.Show("Button clicked!");
}
var customListView = new CustomListView();
customListView.Location = new Point(10, 10);
customListView.Size = new Size(400, 200);
Controls.Add(customListView);
这样,就可以在WinForms中的ListView中添加按钮了。请注意,这只是一个简单的示例,实际应用中可能需要进行更多的优化和调整。
